Asphalt is extremely durable, but similar to most materials, asphalt also needs proper protection from harsh weather conditions. Conditions ranging from jarring sun rays to heavy rains can cause deterioration in the asphalt’s structure.

Routine asphalt resurfacing and rehabilitation is required to reduce its vulnerability towards extremely cold, hot, and wet climate conditions. In order to assist you in protecting your pavement, we have listed a few adverse effects varying weather conditions may have on asphalt.

Cold Temperatures

Winter in Canada brings along freezing temperatures that makes water located above and below asphalt to freeze, causing cracks in the outer layers. An increase in temperature de-freezes the water, allowing it to seep into the cracks and freezing again once the degrees fall. When water is frozen it will expand, causing the cracks in the asphalt to widen, which kick-starts the development of a pothole.

Rainy Days

In addition to expanding, water is also capable of dissolving most materials it remains stationed on. It is absolutely essential for your asphalt paving to have drainage since persistence of moisture can cause grave deterioration. The spring and fall months bring numerous rainy days along with them. Pre-existing cracks in the asphalt can cause water to penetrate the structure and significantly weaken the bond between the pavement’s structure and asphalt binder. Steeper paving serves as a solution to the problem and allows the water to run down the structure.

Hot Temperatures

Asphalt pavements located in warmer climates are also at risk of deterioration. Coarse heat and direct sun rays can cause asphalt to start crumbling. If water remains stationed on the asphalt for an extended period, it can erode the upper layers of the paving. This can cause air to enter and form gaps in the layers beneath. In the event of external pressure caused by the weight of vehicles, it will cause the upper layers to break and disintegrate.

Tips on Protecting your Asphalt

To safeguard asphalt from water damage, you should layer your paving with a sealant once every two to three years. This method will protect it from extreme temperatures and water erosion. Make sure to repair any holes and cracks that occur in your pavement immediately in order to prevent water from seeping in and making them worse. The defects pose a huge hazard to you and your vehicle, while also diminishing the appeal of your property.
